Im 22 years old and about 3 months ago I developed a bump between my V and thigh about wear my panties would go..i thought maybe it was from shaving and it would go away but it has gotten bigger its hard it doesn t hurt til I try to squeeze it and theres a sharp pain and it swells like if you got bit by a mosquito..also I have like a fish smell coming from my V but I have no STD what could these be?
